So I have not bloomed many paphs since I contracted the obsession only about a year ago. On the few plants that have bloomed, I have cut the stalk about an inch from the leaves and all was well afterwards. However, after I cut the stalk on this henryanum the sheath has started turning brown. Is this a Physan20 situation or can I just leave it to dry up and fall off? Rather unsightly IMO. Henryanum on left and Lynleigh Koopowitz on the right for comparison. Thanks in advance for any thoughts.
